2024-10-10pinctrl: sophgo: fix double free in cv1800_pctrl_dt_node_to_map()Harshit Mogalapalli
'map' is allocated using devm_* which takes care of freeing the allocated data, but in error paths there is a call to pinctrl_utils_free_map() which also does kfree(map) which leads to a double free. Use kcalloc() instead of devm_kcalloc() as freeing is manually handled.

Currently if condition (!bo and !vmw_kms_srf_ok()) was met we go to err_out with ret == 0. err_out dereferences vfb if ret == 0, but in our case vfb is still NULL.

Do not validate format equality for the non 3d cases to allow xrgb to argb copies and make sure the dx binding flags are only used on dx compatible surfaces.

2024-10-10of: Skip kunit tests when arm64+ACPI doesn't populate root nodeStephen Boyd
A root node is required to apply DT overlays. A root node is usually present after commit 7b937cc243e5 ("of: Create of_root if no dtb provided by firmware"), except for on arm64 systems booted with ACPI tables. In that case, the root node is intentionally not populated because it would "allow DT devices to be instantiated atop an ACPI base system"[1]. Introduce an OF function that skips the kunit test if the root node isn't populated. Limit the test to when both CONFIG_ARM64 and CONFIG_ACPI are set, because otherwise the lack of a root node is a bug. Make the function private and take a kunit test parameter so that it can't be abused to test for the presence of the root node in non-test code. Use this function to skip tests that require the root node. Currently that's the DT tests and any tests that apply overlays.

2024-10-10vxlan: Handle error of rtnl_register_module().Kuniyuki Iwashima
Since introduced, vxlan_vnifilter_init() has been ignoring the returned value of rtnl_register_module(), which could fail silently. Handling the error allows users to view a module as an all-or-nothing thing in terms of the rtnetlink functionality. This prevents syzkaller from reporting spurious errors from its tests, where OOM often occurs and module is automatically loaded. Let's handle the errors by rtnl_register_many().

2024-10-10s390/ap: Fix CCA crypto card behavior within protected execution environmentHarald Freudenberger
A crypto card comes in 3 flavors: accelerator, CCA co-processor or EP11 co-processor. Within a protected execution environment only the accelerator and EP11 co-processor is supported. However, it is possible to set up a KVM guest with a CCA card and run it as a protected execution guest. There is nothing at the host side which prevents this. Within such a guest, a CCA card is shown as "illicit" and you can't do anything with such a crypto card. Regardless of the unsupported CCA card within a protected execution guest there are a couple of user space applications which unconditional try to run crypto requests to the zcrypt device driver. There was a bug within the AP bus code which allowed such a request to be forwarded to a CCA card where it is finally rejected and the driver reacts with -ENODEV but also triggers an AP bus scan. Together with a retry loop this caused some kind of "hang" of the KVM guest. On startup it caused timeouts and finally led the KVM guest startup fail. Fix that by closing the gap and make sure a CCA card is not usable within a protected execution environment. Another behavior within an protected execution environment with CCA cards was that the se_bind and se_associate AP queue sysfs attributes where shown. The implementation unconditional always added these attributes. Fix that by checking if the card mode is supported within a protected execution environment and only if valid, add the attribute group.

2024-10-10mmc: sdhci-of-dwcmshc: Prevent stale command interrupt handlingMichal Wilczynski
While working with the T-Head 1520 LicheePi4A SoC, certain conditions arose that allowed me to reproduce a race issue in the sdhci code. To reproduce the bug, you need to enable the sdio1 controller in the device tree file `arch/riscv/boot/dts/thead/th1520-lichee-module-4a.dtsi` as follows: &sdio1 { bus-width = <4>; max-frequency = <100000000>; no-sd; no-mmc; broken-cd; cap-sd-highspeed; post-power-on-delay-ms = <50>; status = "okay"; wakeup-source; keep-power-in-suspend; }; When resetting the SoC using the reset button, the following messages appear in the dmesg log: [ 8.164898] mmc2: Got command interrupt 0x00000001 even though no command operation was in progress.

Since the power to the Wi-Fi card, which resides on this SDIO bus, is initially off after the reset, an interrupt SDHCI_INT_TIMEOUT is triggered. Immediately after that, a second interrupt SDHCI_INT_RESPONSE is triggered. Depending on the exact timing, these conditions can trigger the following race problem: 1) The sdhci_cmd_irq top half handles the command as an error. It sets host->cmd to NULL and host->pending_reset to true. 2) The sdhci_thread_irq bottom half is scheduled next and executes faster than the second interrupt handler for SDHCI_INT_RESPONSE. It clears host->pending_reset before the SDHCI_INT_RESPONSE handler runs. 3) The pending interrupt SDHCI_INT_RESPONSE handler gets called, triggering a code path that prints: "mmc2: Got command interrupt 0x00000001 even though no command operation was in progress." To solve this issue, we need to clear pending interrupts when resetting host->pending_reset. This ensures that after sdhci_threaded_irq restores interrupts, there are no pending stale interrupts. The behavior observed here is non-compliant with the SDHCI standard. Place the code in the sdhci-of-dwcmshc driver to account for a hardware-specific quirk instead of the core SDHCI code.

Currently we can call fence_fini() twice if something goes wrong when sending the GuC CT for the tlb request, since we signal the fence and return an error, leading to the caller also calling fini() on the error path in the case of stack version of the flow, which leads to an extra rpm put() which might later cause device to enter suspend when it shouldn't.

He also fixes an out-of-bounds issue when MSI-X are increased for VFs. Wojciech clears FDB entries on reset to match the hardware state. For i40e: Aleksandr adds locking around MACVLAN filters to prevent memory leaks due to concurrency issues.

2024-10-09net: fec: don't save PTP state if PTP is unsupportedWei Fang
Some platforms (such as i.MX25 and i.MX27) do not support PTP, so on these platforms fec_ptp_init() is not called and the related members in fep are not initialized. However, fec_ptp_save_state() is called unconditionally, which causes the kernel to panic. Therefore, add a condition so that fec_ptp_save_state() is not called if PTP is not supported.

pgoff should be aligned using ALIGN_DOWN() instead of ALIGN(). Otherwise, vmf->address not aligned to fault_size will be aligned to the next alignment, that can result in memory failure getting the wrong address. It's a subtle situation that only can be observed in page_mapped_in_vma() after the page is page fault handled by dev_dax_huge_fault. Generally, there is little chance to perform page_mapped_in_vma in dev-dax's page unless in specific error injection to the dax device to trigger an MCE - memory-failure. In that case, page_mapped_in_vma() will be triggered to determine which task is accessing the failure address and kill that task in the end. We used self-developed dax device (which is 2M aligned mapping) , to perform error injection to random address. It turned out that error injected to non-2M-aligned address was causing endless MCE until panic. Because page_mapped_in_vma() kept resulting wrong address and the task accessing the failure address was never killed properly: [ 3783.719419] Memory failure: 0x200c9742: recovery action for dax page: Recovered [ 3784.049006] mce: Uncorrected hardware memory error in user-access at 200c9742380 [ 3784.049190] Memory failure: 0x200c9742: recovery action for dax page: Recovered [ 3784.448042] mce: Uncorrected hardware memory error in user-access at 200c9742380 [ 3784.448186] Memory failure: 0x200c9742: recovery action for dax page: Recovered [ 3784.792026] mce: Uncorrected hardware memory error in user-access at 200c9742380 [ 3784.792179] Memory failure: 0x200c9742: recovery action for dax page: Recovered [ 3785.162502] mce: Uncorrected hardware memory error in user-access at 200c9742380 [ 3785.162633] Memory failure: 0x200c9742: recovery action for dax page: Recovered [ 3785.461116] mce: Uncorrected hardware memory error in user-access at 200c9742380 [ 3785.461247] Memory failure: 0x200c9742: recovery action for dax page: Recovered [ 3785.764730] mce: Uncorrected hardware memory error in user-access at 200c9742380 [ 3785.764859] Memory failure: 0x200c9742: recovery action for dax page: Recovered [ 3786.042128] mce: Uncorrected hardware memory error in user-access at 200c9742380 [ 3786.042259] Memory failure: 0x200c9742: recovery action for dax page: Recovered [ 3786.464293] mce: Uncorrected hardware memory error in user-access at 200c9742380 [ 3786.464423] Memory failure: 0x200c9742: recovery action for dax page: Recovered [ 3786.818090] mce: Uncorrected hardware memory error in user-access at 200c9742380 [ 3786.818217] Memory failure: 0x200c9742: recovery action for dax page: Recovered [ 3787.085297] mce: Uncorrected hardware memory error in user-access at 200c9742380 [ 3787.085424] Memory failure: 0x200c9742: recovery action for dax page: Recovered It took us several weeks to pinpoint this problem,  but we eventually used bpftrace to trace the page fault and mce address and successfully identified the issue.
